The PCI Express port driver uses 'struct pcie_port_service_id' for
matching port service devices and drivers, but this structure
contains fields that duplicate information from the port device
itself (vendor, device, subvendor, subdevice) and fields that are not
used by any existing port service driver (class, class_mask,
drvier_data).  Also, both existing port service drivers (AER and
PCIe HP) don't even use the vendor and device fields for device
matching.  Therefore 'struct pcie_port_service_id' can be removed
altogether and the only useful members of it (port_type, service) can
be introduced directly into the port service device and port service
driver structures.  That simplifies the code quite a bit and reduces
its size.

PCI Express port driver extension, as defined by struct
pcie_port_device_ext in portdrv.h, is allocated and initialized, but
never used (it also is never freed).  Extend it to hold the PCI Express
port type as well as the port interrupt mode, change its name and use it
to simplify the code in portdrv_core.c .

Additionally, remove the redundant interrupt_mode member of struct
pcie_device defined in include/linux/pcieport_if.h .

The 'use pci_find_ext_capability everywhere' cleanup brought a new bug,
which makes the AER stop working.  Fix it by actually using find_ext_cap
instead of just find_cap.  Drop the unused config space size define while
we're at it.

__must_check goes on the declaration, not the definition.

Have pcie_port_bus_register() notice and return errors.
Mark it __must_check so that its caller(s) must check its return value.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
